Science
Mechanism of Action
This extract functions by calming inflammatory factors in the skin, a benefit primarily attributed to its natural content of salicylates like salicin. It delivers antioxidant effects through rich compounds such as flavonoids and phenolic acids. Spiraea Ulmaria is also believed to inhibit the 5-alpha reductase enzyme, which aids in reducing excess sebum. Tannins within the extract provide astringent qualities, helping to refine pores and cleanse the skin. Furthermore, it improves dermal cell proliferation, accelerates renewal rates, and fortifies the skin's barrier against oxidative stress, contributing to healing, evening tone, elasticity, collagen production, and hydration.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Concentrations of 0.5% to 1% are identified as necessary for effectively controlling signs of oily skin.
- 02 Antioxidant and soothing benefits are demonstrated at concentrations significantly lower than 0.5%.
- 03 In vitro assays at extremely low concentrations, specifically 0.00004% to 0.0002%, showed moderate modulation of gene expressions linked to skin barrier function and epidermal renewal.
Transparency
Dusting Analysis
While Spiraea Ulmaria Flower Extract offers antioxidant and soothing properties at lower concentrations, its effectiveness for controlling signs of oily skin necessitates a concentration between 0.5% and 1%. Products claiming significant oil regulation or comprehensive skin renewal at concentrations below 0.5% (especially below 0.1%) may be considered to be dusting, as the concentration may not deliver the full spectrum of advertised benefits.
The Formula
Formulation
Stability
Optimal stability is generally observed within a pH range of 4.0 to 6.5, a suggested range for formulations containing a 20% extract.
Conflicts
- Individuals with a known allergy to salicylates should use this ingredient with caution due to the presence of naturally occurring salicylic acid derivatives.
Safety
Safety Profile
Generally regarded as safe for topical cosmetic application. However, individuals with salicylate allergies should exercise caution. Due to a lack of specific data on topical use during pregnancy or breastfeeding, consultation with a healthcare professional is recommended. Adverse reactions are uncommon, but a patch test is advisable prior to widespread use. EWG Skin Deep indicates a LOW concern for Cancer, Allergies & Immunotoxicity, and Developmental & Reproductive Toxicity, noting a 'limited-fair' volume of research.
